There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This will be a prospective study simulating return to school for two full days prior to the start of the school year in September. Volunteer students and teachers from six grade ranges will be recruited to participate in the study. In each grade range, there will be two classes that will participate, one that will be assigned to wear face masks/coverings at all times (experimental group/class) and the other that will not wear face masks/coverings at all times (control group/class). Students will be randomized to either the masking at all times (experimental across all grades) or no masking (control across JK-Grade 4) / masking only when physical distance can be maintained (control across Grade 5-Grade 12) class in their appropriate grade. Personal behaviours and person-to-person interactions will be recorded using video cameras. In addition, a safe biological indicator will be applied to the hands to simulate potential asymptomatic infection in a subset of students. Other students will have sanitizer applied so that students are blinded to who has the indicator. Cameras will be used to document how the indicator moves throughout the classroom.
Single center, randomized, double-blinded, placebo-controlled, single ascending-dose study for the evaluation of the safety, tolerability, and PK following single oral doses of INV-101.
The purpose of this study is to evaluate the duration of response following withdrawal of ruxolitinib cream (Cohort A vehicle group), safety and maintenance of response with continued use of ruxolitinib cream in participants who have completed either Study NCT04052425 or NCT04057573 (parent studies) in which the participants will have been using ruxolitinib cream BID for the previous 28 to 52 weeks depending on their initial randomization in the parent study.
Current gold standard methodologies for diagnosing type 2 diabetes (T2D) or prediabetes can be unreliable and inaccurate, and require the need for multiple different tests for comparison. It is possible that a simpler and more refined method of diagnosing T2D or prediabetes involves examining the proportional-integral (PI) control system of the body's glycemic function (i.e., a model of the glucose curve). The purpose of this research is to examine how well a PI model can diagnose nondiabetic, prediabetic, or diabetic patients based on glucose data gathered from a wearable glucose monitoring device.
In children and adolescents (older than 6 years in age) who arrive in the pediatric emergency department because they have been having 5 days or less of abdominal pain (possible appendicitis), will patients who are treated with ketorolac get just as much pain relief as those patients treated with morphine? To answer this research question, we will need a large number of patients in a study. To ensure we have enough patients, we must include many hospitals in different cities and provinces in the same study. Before doing this, though, we must first test a smaller version of the study in our center at McMaster Children's hosptial. The goal of doing this at McMaster first is to make sure or understand: 1. We can enroll enough people in our study over 1 year 2. We can make sure that all the information we collect from patients is complete and nothing is missing 3. Reasons behind why people don't want to participate in the study 4. How satisfied patients and their caregivers were with the study
While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.
Being short sighted means that vision is blurry when looking at things far away. People with a condition called "pathologic myopia" are short sighted due to problems in the back layer of their eyes, also known as the retina. Some people with pathologic myopia can develop a serious condition called myopic choroidal neovascularization (mCNV). In people with mCNV, new blood vessels grow into the retina. These blood vessels can break, leaking blood or fluid into the retina. This can cause blurry vision or a loss of vision. In this study, researchers will find out more about how well drug aflibercept works and how safe it is in Canadian patients with mCNV. The researchers in this study will review information from the patients' eye doctor visits. The patients in this study will include Canadian men and women who started receiving aflibercept between May 2017 and August 2019. These patients were at least 18 years old and had not received treatment for their mCNV before. The researchers will look at the results of vision tests to find out how well the patients could read from a distance after they received aflibercept for 6 months. They will compare the results of these tests to before the patients received treatment. They will also learn more about how safe it is to have aflibercept injection into the eye.
The purpose of this prospective randomized controlled trial is to explore the role of a motion sensor with accompany web application on step counts, energy balance, and metabolic markers in nurses. Additionally, eating behaviours, behavioural regulation in exercise, and mood states that may impact these parameters will also be examined.
The primary objective is to demonstrate safety and long-term effectiveness of the irreversible electroporation (IRE) system (Circular IRE Catheter and IRE Generator) when used for isolation of the atrial pulmonary veins (PVs) in treatment of participants with paroxysmal atrial fibrillation (PAF).
Babies born very early (at less than 32 weeks) usually need help to breath right at birth, also called neonatal resuscitation. Healthcare providers (HCPs) are specially trained to provide this help. HCPs uses information about the baby's condition, such heart rate and oxygen levels, to decide whether they giving the baby effective help, or whether other actions are needed. It can be very stressful for even experienced HCPs to interpret all this data, coordinate a team, make decisions, and perform specialized skills all at the same time. More recently, new ways of monitoring how a baby is doing neonatal resuscitation has been studied. Respiratory function monitoring (RFM) is a machine that can measure how much air is going into the lungs. This is important as too much air can lead to lung damage, while too little air means that the baby isn't breathing effectively. Another measure is called cerebral near-infrared spectroscopy (cNIRS), which measures oxygen levels in the brain using a probe placed on the forehead. Providing the right amount of oxygen to the most vulnerable organ - the brain - can be important in lowering the risk for injuries to the brain such as brain bleeding. While these machines give us more information, it can also make it even harder for HCPs to focus on the task, adding more complexity to making decisions, adding to their workload, and causing more stress. To study the effect RFM and cNIRS may have on how affects HCPs workload and stress, the investigators will study HCPs self-reported workload during three time periods - first, doing resuscitations only using basic information (Group 1: heart rate, oxygen levels, direct observations of the baby), second, adding RFM (Group 2), finally adding both RFM and cNIRS (Group 3). A survey called NASA Task Load Index will be used to study HCPs workload. On a small number of teams, the investigators will also track where the leader of the team is looking using eye-tracking glasses, how stressed the leader is by measuring their heart rate, skin sweat, and pupil dilation. Finally, the investigators will collect some information about the baby's resuscitation and hospital stay.
